IMPROVEMENT IN SEWING-MACHINE TREA DLES.

Specification forming part of Letters Patent No. 151,299, dated May 26, 1874; application filed d April 11, 1874.

To all whom it may concern:

Be it known that I, DANIEL E. LILLIs, of Jackson, Jackson county, Michigan, have invented a new and Improved Treadle for Sewing-Machines, of which the following is a specification:

I make the foot-board of my treadlc adjustable to accommodate an ankle or leg movement, as hereinafter described.

Figure 1 is a sectional elevation of my im proved treadle, and Fig. 2 is a horizontal section.

A is the double-cranked treadle rock-shaft; B, the arm for connecting with the crank of the driving-wheel; and O is the movable footboard. Said board is attached to the cranked rod A, so as to shift on it crosswise the length of the slot D, in which is a binding-screw, E, for holding it in any adjustment. F F are guide-rods attached to the foot-board and passing through the rod A, so that they slide therein as the foot-board is adjusted backward and forward. Such adjustment is made to al= v low the operator to so place his feet upon the board as to work it mainly by a swinging leg movement, or mainly by an ankle-movement. In the former case the board G is adjusted toward the operator to the limit of the slot- D,

and in the other case it is adjusted in the op DANL. E. LILLIS.
